People continued to party on Archimedeslaan for a long time, says a man from Groenekan via WhatsApp. “We live quite a distance from it, but it really thunders heavily here.” He said he asked if it could be quieter, but that was not answered. People from Bilthoven, De Bilt and Utrecht also report via email and WhatsApp, probably about the same party, where around a thousand people would have been present at the peak.
